Need Annotation field for student assignments

I woulod like to have students annotate their references as part of their assignment. This would achieve two learning objectives. First, have them reflect on what they found in the reference. Second to allow them to comment in class having made a small effort which they cannot deny they were too busy to do.

To do this I need an Annotation field for all reference types. Please can this be done soon as otherwise I see Mendely on the horizon
